Angiotensin II is an established regulator of vascular tone and smooth muscle cell (SMC) growth. However, there are little data about its effect on collagen synthesis by SMCs and none regarding the mechanism of such an effect. We studied the effect of angiotensin II on collagen production by human arterial SMCs, using uptake of [(3)H]proline into collagenase-digestible proteins, and by ribonucl...

The purpose of this study was to examine in vivo the importance of angiotensin subtype 1 (AT1) versus subtype 2 (AT2) receptors in spontaneously hypertensive (hypertensive) versus normotensive Wistar-Kyoto (control) rats. Intravenous infusions of DuP 753, a selective AT1 receptor antagonist, abolished the pressor responses to intravenous infusions of angiotensin II in both strains, and the pote...

Angiotensin II is an established regulator of vascular tone and smooth muscle cell (SMC) growth. However, there are little data about its effect on collagen synthesis by SMCs and none regarding the mechanism of such an effect. We studied the effect of angiotensin II on collagen production by human arterial SMCs, using uptake of [H]proline into collagenase-digestible proteins, and by ribonucleas...

The renal endothelin system contributes to sex differences in blood pressure with males demonstrating greater endothelin type-A receptor-mediated responses relative to females. Intrauterine growth restriction programs hypertension and enhance renal sensitivity to acute angiotensin II in male growth-restricted rats. Endothelin is reported to work synergistically with angiotensin II. Thus, this s...

AIMS The long-term cardioprotective effect of angiotensin receptor blockers (ARBs) is associated with the short-term lowering of its primary target blood pressure, but also with the lowering of albuminuria. Since the individual blood pressure and albuminuria response to an ARB varies between and within an individual, we tested whether the variability and discordance in systolic blood pressure (...

The aim of this study was to explore the regulation of angiotensin receptors after chronic infusion with angiotensin II (Ang II) and to clarify the relative roles of the angiotensin type 1 (AT(1)) and type 2 (AT(2)) receptors in the mediation of Ang II-induced mesenteric vascular hypertrophy. In male Sprague-Dawley rats, Ang II infusion at a dose of 58.3 ng/min by subcutaneous osmotic minipumps...

conclusions spironolactone combined with aceis or arbs leads to reduction of proteinuria in chronic kidney disease and therefore reduction of progression of the disease. objectives the study was designed to assess the effects of spironolactone as the aldosterone antagonist combined with acei or arb drugs to reduce proteinuria in chronic kidney disease to prevent its progression. patients and me...

「2021年JCS/JHFSガイドライン フォーカスアップデート版 急性・慢性心不全診療」の治療アルゴリズムにおいて，HFrEF（heart failure with reduced ejection fraction）患者の治療戦略が大きく改訂された．具体的には，従来の慢性心不全の標準治療であったACE（angiotensin-converting enzyme）阻害薬/ARB（angiotensin II receptor blocker）＋β遮断薬＋MRA（mineralocorticoid antagonist）の3剤併用療法からACE阻害薬/ARB/ARNI（angiotensin neprilysin inhibitor）＋β遮断薬＋MRA＋SGLT2（sodium glucose cotransporter 2）阻害薬の4剤併用療法への移行が示されている．

Losartan potassium, Valsartan , Telmisartan and Irbesartan are angiotensin-II-receptor antagonists (ARA II) group which used in treatment of hypertension alone or in combination with other drugs mainly Hydrochlorothiazide. RP- HPLC method was developed for the assay of three angiotensin-II-receptor antagonists (ARA-IIs) in presence of Hydrochlorothiazide. The method was performed by reversed ph...
